A series of 0-D, 1-D, and 2-D metal-organic compounds through reactions of quinoline-2,3-dicarboxylic acid (2,3-H(2)qldc) with transition metal salts MCl(2), namely, M(2,3-Hqldc)(2)(H(2)O)(2) (M = Co(1), Zn(4) and Cd(7)), [M(3-qlc)(2)(H(2)O)(2)](n) (M = Co(2), Zn(5) and Cd(8)), M(2-qldc-3-OCH(3))(2)(CH(3)OH)(2) (M = Co(3) and Zn(6)) and [Cd(2,3-qldc-OCH(3))(μ(2)-Cl)](2n) (9) (where, 3-Hqlc = qu...

The title new diquinaldine derivative, C27H24N4, forms molecular assemblies organized by intermolecular quinoline pi-pi stacking [3.356 (3) and 3.440 (3) A] and both inter- and intramolecular N-H...N hydrogen bonds [3.039 (3)-3.104 (3) A and 129 (2)-172 (2) degrees]. The combination of such interactions provides readily definable contacts that propagate along each crystallographic axis.

In the mononuclear title complex, [CdBr2(C20H17N3)(C3H7NO)], synthesized from the quinoline-derived Schiff base 2-(1H-indol-3-yl)-N-(quinolin-2-yl-methyl-ene)ethan-amine (IQME), the coordination geometry around the Cd(2+) atom is distorted trigonal bipyramidal, the axial positions being occupied by the quinoline N atom [Cd-N = 2.401 (3) Å] and one di-methyl-formamide O-atom donor [Cd-O = 2.399 ...

Skimmia laureola Hook (Rutaceae) is found in Kashmir and in the mountains of Northern Pakistan and is used in folklore medicine for the treatment of various ailments [1 – 3]. The quinoline alkaloids of this plant have demonstrated antifungal and immunomodulating properties [4, 5]. The ethanolic extracts of the aerial parts of S. laureola are active against the animal pathogen Microsporium canis...

gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...

We herein described an intramolecular imino Diels-Alder reaction promoted with BF(3).OEt(2)/DDQ affording substituted quinolines. Using this procedure, we prepared the chiral quinoline moiety of the uncialamycin, a new enediyne natural product.

In the title compound, C18H13N3O2·H2O, the oxa-diazole ring forms dihedral angles 7.21 (10) and 21.25 (11)° with the quinoline and benzene rings, respectively. The crystal structure features O-H⋯N hydrogen bonds and is further consolidated by C-H⋯O hydrogen-bonding inter-actions involving the water molecule of hydration.

In the title compound, C(24)H(19)N(3)O, the pyrazole ring is close to being planar (r.m.s. deviation of the five fitted atoms = 0.062 Å), and each of the N-bound quinoline ring [dihedral angle = 9.90 (7)°] and the C-bound phenyl ring in the 3-position is close to being coplanar [dihedral angle = 8.87 (9)°]. However, the phenyl ring in the 5-position forms a dihedral angle of 72.31 (9)°. The hy-...
